Myeloperoxidase (MPO), which is located within neutrophils capable of producing hypochlorous acid, is active in vitro against bacteria and fungi. However, MPO-deficient persons are usually healthy. To define the in vivo contribution of MPO to early host defense against pulmonary infections, MPO-deficient and control mice were intranasally infected with various fungi and bacteria, and the number of residual microorganisms in lungs was compared 48 h later. MPO-deficient mice showed severely reduced cytotoxicity to Candida albicans, Candida tropicalis, Trichosporon asahii, and Pseudomonas aeruginosa. However, the mutant mice showed a slight but significantly delayed clearance of Aspergillus fumigatus and Klebsiella pneumoniae and had comparable levels of resistance to the wild type against Candida glabrata, Cryptococcus neoformans, Staphylococcus aureus, and Streptococcus pneumoniae. These results suggest that the MPO-dependent oxidative system is important for host defense against fungi and bacteria, although the effect varies by pathogen species.
